1. projectile motion MOTION i n two dimensions

2. What is projectile MOTION?

3. If there is no force acting on an object , then it will continue moving at a constant speed in the same direction. - there will be no change in its velocity Horizontal Motion - distance will increase the same amount with each second

4. Free Fall Revisited An object in free fall is only acted on by gravity - Acceleration due to gravity is 9.8 m/s 2 - distance covered increases with each second

5. Projectile Motion Combines Vertical Motion and Horizontal Motion The vertical motion of a projectile is not affected by its horizontal motion -meaning: The vertical motion of a projectile is identical to an object in free fall The horizontal motion of a projectile is not affected by its vertical motion - meaning the projectile will travel the same horizontal distance as it would if it were simply rolling on a flat surface in the absence of friction

6. Projectile Calculations Horizontal Distance d = v(t) Horizontal Velocity v f = v i + at Vertical Distance d = v i t + ½ gt 2 Vertical Velocity V f = V i + gt

7. What is the path of a projectile called?

8. Is projectile motion one dimensional? No, it is 2 dimensional- vertical and horizontal

9. What force(s) is acting on the projectile? Gravity only

10. Which direction, horizontal or vertical has acceleration ? Which direction, horizontal or vertical has constant speed? Vertical Horizontal
